Abstract: Fibre reinforced cement-based composites is a large group of composites with a variety of properties. The purpose of adding fibres is to overcome the brittleness of the concrete by improving the post-cracking behaviour and enhancing ductility. This paper deals with the group Strain-hardening Cement-based Composites (SHCC) which exhibits excellent mechanical behaviour showing tensile strain-hardening and multiple fine cracks. The primary objective of the presented research is to verify a developed constitutive model utilised within the nonlinear and sequentially linear framework. Specifically, this paper presents the studies involving the tree-point bending test and the shear behaviour of reinforced SHCC elements tested on beam specimens monotonically loaded by an anti-symmetrical moment.
